The novel composite material of the present invention can exhibit excellent thermal and mechanical properties while maintaining properties as a mono material so that it is widely applicable to major uses for polymer materials.

TECHNICAL FIELD

The present invention relates to a novel polymeric composite material which comprises two or more polymers having a cyclic monomer unit. More particularly, the present invention relates to a novel polymeric composite material which comprises a resin composition containing at least two polymers selected from the group consisting of a polymer having a cyclic conjugated diene monomer unit and/or a cyclic olefin monomer unit and a modified polymer thereof, or which comprises a resin composition containing other polymers which are further added to the resin composition according to desire.

BACKGROUND ART

In research on a polymeric material which can be used as an industrial material, many studies have been conducted to find materials which exhibit excellent heat resistance and mechanical strength. As a result, various types of material have been proposed.

These polymeric materials are used in a wide variety of fields such as an automobile part, an electrical part, an aircraft and space part, sports and leisure goods and general variety goods because they have outstanding features of being light, of being shaped highly freely and of exhibiting various properties according to the types of use. Their importance has drastically increased because of market demand and the progress of scientific techniques.

However, one of the most important problems to be solved when such polymeric materials are used as an industrial material in a wide range of applications is the fact that the mechanical properties of an organic polymeric material change considerably depending on the temperature of the atmosphere during use.

It is believed that the major cause of this problem is that the polymer chains are converted to a rubber state from a glass state when the atmosphere temperature in use reaches the region above the glass transition temperature (Tg) of the polymer.

Therefore, it is essentially impossible to solve this problem by using a polymeric material having a single molecular structure so that heretofore many studies have been conducted to solve this problem by combining plural polymeric materials.

For example, as one of the specific methods to solve this problem, an attempt to obtain polymeric materials having low sensitivity to atmosphere temperature has often been made by compounding or copolymerizing one polymeric material with other polymers having a different Tg in order to improve the mechanical properties of the polymeric material (e.g., rigidity at a high temperature, impact resistance, strength at a high temperature and dimensional stability).

However, in prior art wherein the above attempt has been made, it is necessary to diversify the types of polymers to be compounded according to the improvement purposes. This does not always satisfy a market demand for making the number of types of polymeric materials used as an industrial material as small as possible.

Therefore, aggressive studies on (hydrogenated) conjugated diene type polymers such as polybutadiene and polyisoprene, which are representative components contained in composite materials, have been made. Since the conjugated diene type polymers can be subjected to living anionic polymerization, they have high degrees-of-freedom of polymer chain design and their material properties are controlled relatively easily. When they are used as an improvement material for the composite material, they have the possibility to impart rigidity at a high temperature, impact strength, strength at a high temperature, dimensional stability and the like by compounding or copolymerizing the same type materials.

There is currently a strong demand for development of a conjugated diene type polymeric material having higher thermal properties (melting point, glass transition temperature, heat distortion temperature and the like) and mechanical properties (tensile modulus, flexural modulus and the like).

As one of the most effective methods to solve this problem, investigations on a method for obtaining an excellent composite material improved in necessary properties using only the same type of polymer is usually carried out. Such a method comprises introducing a cyclic monomer unit into a polymer chain of the conjugated diene type polymer to improve the structure of the polymer chain of the conjugated diene type polymer by homopolymerizing or copolymerizing not only a monomer having relatively small steric hindrance such as butadiene and isoprene but also a monomer having large steric hindrance, i.e., a cyclic conjugated diene type monomer, and further by conducting hydrogenation, if necessary; synthesizing a polymer optionally having high thermal properties (rigidity and strength), impact strength and dimensional stability in the same type of polymer (a conjugated diene type polymer); and compounding the thus-obtained polymers with each other or with other polymers.

Although the prior art has proposed catalysts exhibiting polymerization activity satisfactory to some extent for the monomer having relatively small steric hindrance such as butadiene and isoprene, there has not been found a catalyst exhibiting fully satisfactory polymerization activity for the monomer having large steric hindrance, i.e., the cyclic conjugated diene type monomer.

Die Makromolekulare Chemie., 163, 13 (1973) discloses cyclohexadiene homopolymer obtained by polymerizing 1,3-cyclohexadiene using a large amount of an organic lithium compound as a catalyst. The oligomer obtained therein has a number-average molecular weight of no more than 6,500.

There is also disclosed hydrogenated cyclohexadiene homopolymer (polycyclohexane) having a low molecular weight, which is obtained by hydrogenating the carbon-carbon double bonds of this oligomer with extremely excessive amounts of paratoluene sulfonyl hydrazide. However, the hydrogenated polymer disclosed therein has an extremely low molecular weight. The disclosed hydrogenation method also has a serious problem of great economic disadvantages because of a stoichiometric reaction.

J. Polym. Sci, Polym. Chem. Ed., 20, 901 (1982) discloses cyclohexadiene homopolymer obtained by polymerizing 1,3-cyclohexadiene using an organic sodium compound as a catalyst. The organic sodium used therein is sodium naphthalene. A dianion produced from two radical anions is a polymerization initiator point. In other words, although the cyclohexadiene homopolymer reported therein seemingly has a number-average molecular weight of 38,700, it actually has molecular chains having a number-average molecular weight of 19,350 which grow from the polymerization initiator point in two directions. The polymerization method disclosed in this reference is not industrially useful because the polymerization is conducted at an extremely low temperature.

Makromol. Chem., 191, 2743 (1990) discloses a method for polymerizing 1,3-cyclohexadiene by using polystyryl lithium as an initiator. The polymerization method disclosed in this reference suggests that a transfer reaction with abstraction of a lithium cation and an elimination reaction of a lithium hydride often occurs during the polymerization reaction. It was reported that a block polymer of styrene-cyclohexadiene was not obtained at room temperature and only cyclohexadiene homopolymer having a low molecular weight was obtained though the polymerization reaction is conducted using polystyryl lithium as an initiator.

It was also reported that when block polymerization is conducted at -10° C. with polystyryl lithium, a block copolymer of styrene-cyclohexadiene having a molecular weight of about 20,000 was obtained with cyclohexadiene homopolymer at a considerably low yield.

However, the copolymer obtained has an extremely small content of a cyclohexadiene block. Moreover, this document neither suggests nor teaches a block copolymer containing a chain conjugated diene type monomer, a multiblock of a triblock or more, a radial block and the like.

U.S. Pat. No. 4,127,710 discloses a polymer mixture obtained by polymerizing a monomer mixture containing 1,3-cyclohexadiene, styrene and butadiene with a multifunctional initiator. However, U.S. Pat. No. 4,127,710 not only teaches that the yield of the polymer mixture obtained decreases with an increase of the ratio of 1,3-cyclohexadiene in the monomer mixture, but also fails to provide a cyclohexadiene homopolymer having a high molecular weight, a cyclohexadiene type block copolymer and particularly a block copolymer having a triblock or more. Further, this patent neither suggests nor discloses a composite material of cyclohexadiene type polymers.

U.S. Pat. No. 4,138,536 discloses a polymer mixture obtained by polymerizing a monomer mixture containing 1,3-cyclohexadiene and styrene with a multifunctional initiator. However, U.S. Pat. No. 4,138,536 not only teaches that the yield of the polymer mixture obtained decreases with an increase of the ratio of 1,3-cyclohexadiene in the monomer mixture, but also fails to provide a cyclohexadiene homopolymer having a high molecular weight, a cyclohexadiene type block copolymer and particularly a block copolymer having a triblock or more. Further, this patent neither suggests nor discloses a composite material of cyclohexadiene type polymers.

U.S. Pat. No. 4,179,480 discloses a composition of a styrene-butadiene-styrene block copolymer and a polymer mixture obtained by polymerizing a monomer mixture containing 1,3-cyclohexadiene, styrene and butadiene with a multifunctional initiator. However, the composition disclosed therein does not include a composition of cyclohexadiene type polymers. Particularly, U.S. Pat. No. 4,179,480 neither suggests nor teaches a composite material of cyclohexadiene type block copolymers.

As explained above, the prior art has not succeeded in obtaining an excellent polymeric composite material comprising a polymer having a cyclic monomer unit which is fully satisfactory as an industrial material.

When Polymer I is a hydrogenated polymer, the most preferable method for preparing the hydrogenated polymer is a method which comprises conducting the hydrogenating reaction in the presence of a hydrogenation catalyst after the polymerization reaction of Polymer I reaches a predetermined polymerization rate to hydrogenate a part of or the whole of the carbon-carbon unsaturated bonds contained in the polymer.

Such a method includes:

a batch production method of a hydrogenated polymer comprising deactivating a polymerization catalyst to stop the polymerization reaction, charging a hydrogenation catalyst to the reactor used in the polymerization reaction and introducing hydrogen;

a semi-batch production method of a hydrogenated polymer comprising deactivating a polymerization catalyst to stop the polymerization reaction, transferring the polymer solution to a reactor different from that used for the polymerization adding a hydrogenation catalyst to the reactor, and introducing hydrogen gas into the reactor;

a continuous production method of a hydrogenated polymer comprising continuously conducting a polymerization and a hydrogenation in a tube type reactor.

The hydrogenation of the present invention is conducted in the presence of Polymer I to be hydrogenated and a hydrogenation catalyst under hydrogen atmosphere.

The method for conducting the hydrogenation in the present invention generally comprises maintaining a polymerization solution at a predetermined temperature under an atmosphere of hydrogen or an inert gas, adding a hydrogenation catalyst with or without stirring, introducing a hydrogen gas, and applying pressure to a certain degree.

Conventionally known techniques are employed for the hydrogenation reaction. For example, batch hydrogenation, semi-batch hydrogenation, continuous hydrogenation and a combination thereof can be employed.

The hydrogenation catalyst applicable to the hydrogenation reaction of the present invention includes a uniform hydrogenation catalyst (an organic metallic compound and an organic metal complex) and a nonuniform hydrogenation catalyst (a solid catalyst) which contain at least one metal selected from transition metals or rare earth metals belonging to Groups VI A to VIII in the Periodic Table, and preferably, the former uniform hydrogenation catalyst or a carrier type solid catalyst carrying a transition metal belonging to Group VIII. These catalysts are used individually or in combination.

The nonuniform hydrogenation catalyst may be carried by an inorganic compound such as silica and zeolite or an organic polymer compound, such as cross-linked polystyrene or an organic polymer compound.

Preferred metals contained in the hydrogenation catalyst to be used in the present invention include titanium, cobalt, nickel, ruthenium, rhodium and palladium.

To make these metals into uniform hydrogenation catalysts, it is necessary for the metals to be coordinated or linked with a ligand such as hydrogen, halogen, a nitrogen compound and an organic compound. A combination is optionally determined, but at least a combination, in which a uniform hydrogenation catalyst is soluble in a solvent, is preferable.

Specific examples of the ligand include hydrogen, fluorine, chlorine, bromine, nitrogen monoxide, carbon monoxide, an organic compound containing functional groups such as hydroxyl, ether, amine, thiol, phosphine, carbonyl, olefin and diene and a non-polar organic compound which does not contain functional groups. These ligands may be used individually or in combination.

When the hydrogenation catalyst is a uniform hydrogenation catalyst containing at least one metal selected from transition metals or rare earth metals which belong to Groups VI A to VIII, it is most preferable in view of industrial use to employ a composite catalyst comprising the above hydrogenation catalyst and an organic metal compound containing at least one metal selected from Groups I A to II A and III B metals such as lithium alkyl, magnesium alkyl and aluminum alkyl.

The amount of the hydrogenation catalyst used, which is represented by the concentration of metallic atom based on the polymer to be hydrogenated, is generally 0.1 to 100,000 ppm, preferably 1 to 50,000 ppm, more preferably 5 to 10,000 ppm, particularly preferably 10 to 10,000 ppm. When the amount of the hydrogenation catalyst used is small, the reaction rate is not sufficient. When it is large, economic disadvantages are encountered though the reaction rate is enhanced. In this case, separation recovery of the catalyst is required and the influence of the catalyst residue on the polymer cannot be avoided.

The solvent to be used for the hydrogenation reaction is preferably inactive against the hydrogenation catalyst and can dissolve a polymer. Industrially, an aliphatic hydrocarbon type solvent, an alicyclic hydrocarbon type solvent and an aromatic hydrocarbon solvent are preferred. Of these, an aliphatic hydrocarbon type solvent and an alicyclic hydrocarbon solvent or a mixed solvent thereof are most preferred.

From the industrial point of view, it is most preferred that solvents used in a polymerization reaction and a hydrogenation reaction are the same since an economic advantage is achieved by successively conducting the hydrogenation reaction after the polymerization.

The concentration of the polymer in the polymer solution during the hydrogenation reaction is normally 1 to 90 wt. %, preferably 2 to 60 wt. %, more preferably 5 to 40 wt. %. A low concentration is economically disadvantageous. A high concentration unpreferably enhances the viscosity of the polymer solution and reduces the reaction rate.

The temperature of the hydrogenation reaction is generally -78° to 500° C., preferably -10° to 300° C., most preferably 20° to 250° C. When the reaction temperature is too low, a high reaction rate cannot be achieved. When it is too high, the hydrogenation catalyst is unpreferably deactivated or the polymer is unpreferably deteriorated.

The pressure of the hydrogenation reaction system in the production method of hydrogenated Polymer I is 0.1 to 500 kg/cm² G, preferably 1 to 400 kg/cm² G, particularly preferably 2 to 3,000 kg/cm² G. When the pressure is too low, a sufficiently high reaction rate cannot be attained. A too high pressure is not economically advantageous since an expensive pressure resistant reactor is necessary as an apparatus, and it unpreferably causes hydrogenation decomposition of the polymer.

The time required for the hydrogenation is usually 5 minutes to 240 hours.

After the hydrogenation is complete, the hydrogenation catalyst can be separated from the reaction liquid and recovered by means of conventionally known methods, if desired.

In the method for producing Hydrogenated Polymer I, conventionally known techniques which are commonly used for recovering a polymer from a polymer solution comprising a known polymer can be employed in order to separate and recover Hydrogenation Polymer I from a polymer solution.

Such conventional methods include, for example, a water vapor coagulation method wherein water vapor is directly contacted with a reaction solution, reprecipitation method wherein a poor solvent of a polymer is added to a reaction solution to precipitate the polymer, a method wherein a reaction solution is heated in a vessel to distill off the solvent, a method wherein a polymer is pelletized using a vented extruder while distilling off the solvent, and a method wherein a reaction solution is charged into hot water and pelletizing the polymer using a vented extruder while distilling off the solvent and water. A most suitable method can be selected from the above methods according to the type of Polymer I and the properties of solvent to be used.

When Polymer I contains a carbon-carbon unsaturated bond in its polymer chain, conventional addition reactions for a carbon-carbon double bond other than the hydrogenation reaction may be conducted, if necessary. Using known reaction reagents, there is added, according to the known reaction, at least one substituting group selected from the first group consisting of a halogen atom, sulfur, boron, an alkyl group having 1 to 20 carbon atoms, an unsaturated aliphatic hydrocarbon group having 2 to 20 carbon atoms, an aryl group having 5 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, a cyclodienyl group having 4 to 20 carbon atoms, a heterocyclic group having a 5 to 10-membered ring which contains at least one nitrogen, oxygen or sulfur as a hetero atom, the second group consisting of a hydroxyl group, a thiol group, a thiocyanate group, an ether group (an epoxy group and the like), a thioether group, a thiocarbonic acid group, a formyl group, a carboxyl group, an carbonyl group, an amino group, an imino group, a nitrosyl group, an isocyanate group, a sulfonic acid group, a phosphoric acid group, a phosphonic acid group, a phosphinic acid group and a silyl group, and the third group consisting of an alkyl group having 1 to 20 carbon atoms and linked with the second group, an unsaturated aliphatic hydrocarbon group having 2 to 20 carbon atoms and linked with the second group, an aryl group having 5 to 20 carbon atoms and linked with the second group, a cycloalkyl group having 3 to 20 carbon atoms and linked with the second group, a cyclodienyl group having 4 to 20 carbon atoms and linked with the second group, or a heterocyclic group having a 5 to 10-membered ring which contains at least one nitrogen, oxygen or sulfur as a hetero atom and linked with the second group. However, this is not particularly restricted.

Modified Polymer I is a modified polymer prepared by adding one or more functional groups containing at least one element selected from the group consisting of oxygen (O), nitrogen (N), silicon (Si), sulfur (S), phosphorus (P), and halogen (F, Cl, Br, I) or an organic compound residual group containing the functional groups to Polymer I.

A method for adding the functional groups or the organic compound residual groups containing functional groups can be conducted according to the conventional methods. Such methods include a method wherein the functional groups or the organic compound residual groups containing functional groups are added in the form of a solution, a melt or a solid in accordance with an ene reaction; a method wherein the functional groups or the organic compound residual groups containing the functional groups are added in the presence or absence of a radical generating agent in accordance with a radical reaction; a method wherein the functional groups or the organic compound residual groups containing functional groups (silyl groups) are added in accordance with a hydrosilylation; a method wherein the functional groups or the organic compound residual groups containing functional groups are added to polymer ends (one end, both ends or the like) by conducting living anion polymerization; and the like.

The added amount of the functional groups or the organic compound residual groups containing functional groups in Modified Polymer I is usually 0.001 to 100 wt. %, preferably 0.005 to 80 wt. %, more preferably 0.01 to 50 wt. %, particularly preferably 0.05 to 40 wt. %, most preferably 0.1 to 20 wt. %, based on Modified Polymer I.
